Title: An improved transformer for constant secondary voltage with varying network voltage
IPC: G05F3/06
Filed: 1925-10-12
Abstract: 255,688. Wichnevsky, G. Sokolow-. Oct. 12, 1925. Transformers. - To obtain constant voltage for electric measure. ments from variable voltage supply mains, such as a town supply, a transformer is used having a core with three limbs 1, 2, 3. The limb 1 is saturated and the limbs 2, 3 are not saturated. The main part a of the primary winding is wound on the saturated limb and additional regulating windings b, c are placed on one. or both of the unsaturated limbs; the regulating windings are in series with the main winding and may assist or oppose this winding. The secondary consists of a winding on at least one of the unsaturated limbs; it may be on two or on all the limbs. In each case the winding is arranged so that the resultant electromotive force produced is constant; where the secondary winding is on one limb only the flux therein-by the arrangement of the regulating primary winding-is kept constant, but where the secondary is on two or more limbs the flux through each limb may vary with variable supply voltage the resultant however being constant. An air gap 8, the width of which is decided experimentally, is left between the limb 2 and the cross bar 7. A gap 9 is made in the saturated limb to make the flux curve approximately straight. The laminations of the limb 1 are displaceable for the same purposes.

Abstract: 581,960. Steam and gas turbine plant. BAILEY, R. W., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 5, 1938, No. 25945. [Class 110 (iii)] [Also in Group XXVII] In a combustion-product generator of the kind comprising a supercharged piston-type internal-combustion engine 1 driving an air compressor 2 furnishing the air required by the engine, the two components operating as a unit doing no external work, a turbine 9 is adapted to be supplied with motive fluid from the generator itself or another like generator and to supplement the engine 1 in driving the compressor. The combustion products from the engine may be conveyed by a main 6 to a gas turbine supplying about one-third of the mechanical output of the generator, the remainder being supplied by a turbine driven by steam generated from the heat of additional fuel burnt in the gases delivered from the main 6 to a steam generator as described in Specification 459,365. The turbine 9 may be supplied from the main 6 through a conduit 14 having a branch 17 through which compressed air may be supplied to the turbine 9 for starting. The turbine 9 is connected to the compressor 2 through reduction gearing 13 and a clutch 10 operated automatically or by mechanism 11 having an operating member 12. In the form shown, the plant is controlled by a floating link 22 connected at one end to a governor 19 driven from the shaft of the generator 1, 2 and at the other end to a piston 23 controlled by the pressure in the main 6. A link 27 controls the clutch-operating member 12 and the admission valve 15 to the turbine 9, and a link 28 is connected to a lever 5 controlling the fuel admission pump 4 of the engine 1. Fixed stops 29 limit the movement of the link 22. In modifications, (a) the admission valve 15 of the turbine 9 is controlled by an independent governor driven from the generator 1, 2 ; (b) a number of generators deliver into a common gas main and the control gear is adjusted so that individual generators come into and out of operation in a predetermined order ; (c) the clutch 10 may be of the automatic form shown in Fig. 2, in which a shaft 34 coupled directly to the shaft of the generator 1, 2 carries a clutch member 35 provided with clutch dogs 36 normally urged radially outwards by spring pressure into engagement with abutments in the rim 38 of a clutch member 37 geared to the shaft 41 of the turbine 9. The dogs 36 are weighted so as to be withdrawn by centrifugal action above a predetermined speed of the generator shaft.

Title: Processes for the manufactrue of slub effect yarns

Filed: 1972-06-05
Abstract: 1426876 Spinning yarns IMPERIAL CHEMICAL INDUSTRIES LTD 25 May 1973 [5 June 1972] 26135/72 Headings D1F and D1W Composite slub yarn is produced by supplying a first core yarn to a turbulence chamber under conditions of zero overfeed so that no bulk is imparted to the yarn and injecting a second effect yarn under conditions of (positive) overfeed e.g. 60-120%, by the action of a fluid jet (the fluid being permitted to exhaust from yarn inlet and exit passages of the chamber) forwarding the resultant yarn through an intermingling jet and finally winding. In the chamber, the effect yarn becomes looped and entangled and, at random intervals, attached in the form of balls to the core yarn: in the intermingling jet the effect yarn is locked into the core yarn. The slub effect e.g. the length and distribution of the slubs, may vary according to the angle between the yarn emerging from the intermingling jet and the axis of the yarn passageway therein and/or the angle between the axes of the intermingler and chamber yarn passageways which latter is such as to allow some fluid exhausting from the intermingler to enter the outlet passageway of the chamber. The core and/or effect yarns may be bulked, staple or continuous filament of cellulose acetate, acrylics, polyamide, rayon, cotton or wool. In the apparatus shown, yarn 1 drawn from package 2 passes through guide 3, optionally feed rolls 15, 16, into a turbulent chamber 4 and through stepped inlet and exit yarn passageways 5 and 6 thereof. Inlet 5 may be cylindrical, conical or of square cross-section, baffled or unbaffled, open or restricted at the entrance. Effect yarn 11 from package 12 passes through a guide 13, optionally feed rolls (not shown), an air disperser 14 and into chamber 4. Combined yarn passes through an intermingler 8, around a free-running roller 9, optionally through a steam heater 17, through a guide 10 to wind-up.
